METALLIC DOOR.

speciaqauon t Letters Patent. Application filed June 23, 1908. Serial No. 438,905.

Be it 'known that I, EDWARDG. BUDD, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and Statefof Pennsylvama, have invented 4'a certain new yand useful Improvement in lMetallic Doors, (Case B,) of ivhichthe'fol# lowing is a specification'. y.

'A This invention relates -to metallic Vdoors 'adapted particularly for use as side or end The object ofthe invention is to provide ametallic door of -improved construction,

' such that it lmay be manufactured at low cost and possesses greatstrength and stii ness.

` l'f haveillustrated the preferred embodi- 'ment ofin invent-lon in the accompanying Figure Al is a plan vleiv`of the door; Fig. 2V is a 'l'ongi'tudinal'sect-ion on line 2--2 of l Fig. 1; Fig'. 3 is a transverse section online of Fig. 1; Fig. 4 is a vievy similar to ""Fi'g.y 3, illustrating 'a modification; and Fig.

5 is a. sectional detail view on line'f-' of Referring to these drawings, tlie door has une.o1'-.tivo side walls," each consistin of a piece of sheet-metal cut to the shape esired for the completed door. vIn Figsh 3 and 4 5, I have shown the door as provided with -prefcrnbl y but one such side wall, the other side of the door being open. The sheet-metal piece 1, constituting the sidewall of the door, has edge pieces 2 secured thereto, one at each of the edges of the side wall 1. Each of the four edge pieces 2 is a strip of sheetnieta-l pressed to a U-shuped cross-section, and the.

flange at one edge of each piece 2 is secured to lthe side wall 1 in any suitablemanner, as by welding it or riveting it thereto. The meeting ends of euch pair of adjacent edge strips 2 are mitered as shown by the dotted .line B in Fi 1, and these endsareunited.

Ey welding them together. so

that the line of the joint does not show on the exterior of the door.

ln order to stifen the construction, I employ a plurality of strips 4 secured to the the side wall-1 and extendin g across the same. These stieners are preferably made from sheet-metal strips which are pressed to U-shaped cross-section,

s 1, of a size and shape correspondin size and shape desired for the win ow.v A- frame 8, Whichmay beleither a castinggor a Patented oct. 25,1910.

as shownin 11g.2, and they maybe secured to the side wall 1 by ineansof rivets or'I b -welding them to the side wall. AEaehend of auch of the Stifte-ners 4 extends to the edge of the door at the bottoni of thelUf of the edge strip at the edge of the doorv and' the4 metal at the end of the stitfener is'c'ut to provide an integral extension 5, which inay be turned dowmx'ardly as shown jin Fig. 2 and bese'cured to the bottom ofthe U-sha4 ed edge strip upon the inner face thereof. 'Ehe stiifenels 4 are preferably of such size that .when one of the side walls 6v thereof lies adjacent. to theside wall l, the. other-side wall 7 of the strip lies inthe same plane as the flanges of the edge strips 2distant from the side wall 1, as shown in Fig. 5.a At ea'ch end of the stien'er, the sidewall 7 is out away for a short distance back and `thisend of wallx'? is united to the edge'stri 2 by brazing;`l` or soldering, so as to strengt en the construction, as shown in Fig. 5. A window is provided in the 4door, but preferably this. c ose. i For l this is not arranged to open and purposetan opening iscut 1n the sidejwfall sheet-metal strip, 'is th'en secured.v to the inner face of the side wall 1 at Athe edgeof the opening therein. This frame 8 is rovided with a wall extending inwardly o t e frame, Iagainst which a panel, such as a pane of glass, 9, may be positioned. The glass .9 when out to the proper shape, has a strip oi soft material, such as felt or rubber, applied vabout the edge thereof and is then mounted within the frame 8 against the wall of the frame provided for positioning the glass. Inthis position the glass 9 is heldby a fastening strip 1()` which is secured to theframe 8 by` screws 11 in a. position' to hold the glass i) firmly against rattling. When a casting is employed for the frame 8, this is preferably so shaped as to provide offsets 12 at opposite sides 'thereof` which extend outwardly into the U-shapededge stri s 2, und these offsets are so formed as to fil the 'edge strips 2 along a port-ion of the length of the latter,lso esto maintain them in the proper'shape and position.

If desired, the door may have t'wo side lwalls 1, instead ofouly ont` as' shown in `to the sol Figs. 1, 2, 3 and 5, this construction being illustrated in Fig. 4. Referring to this figure, it will be seen that the two side walls 1 have their edges inclosed within the U- sha ed edge strips 2. In this door, the sti 'ening strips 4 are made somewhat narrower, so that the will fit Within the s ace between the two s1de walls 1. The win owframe 13 is also made somewhat narrower,

so that it will lie between the side Walls 1.v The opening for the Window in one of the side Wallslis made soniewhatlarger than the opening in the other, and one of these side walls is secured to one side of the frame 13, while thefother side Wal-l is secured to the opposite side. Frame 13is provided with lateral offsets 14, which extend into the edge i strips 2 between the side walls 1. The pane of glass 9 is positioned within the frame 13 in the manner above described in connection with Fig. 3.

In Fig. 4, a modification of the shape of the edge strips 2 is shown, by means of which rough edges are avoded, such as would'be apt to catch on and tear the clothes.

In accordance with this construction, the

lateral edges of each of the edge strips 2 are bowed'- outwardly and then inwardly, so as to form a bead` at each edge of each strip 2 and to carry the edge of the strip squarely against the side wall of the door, so that it is not exposed in a. osition Where b urs thereon might catch on t e clothes.

The door shown in the drawings is adapted to slide in the plane in which it lies to open and close it; for this purpose, it is provided with rollers 15 mounted in bearing-blocks secured 'to the interior of the top and bottoni edge strips 2 with the rollers projecting through openings therein. It desired, however, the door may be arranged to swing on hinges secured to the edge strip 'at one side of the door.

Having now described my invention` what I claim as new therein and desire to secure.

by Letters Patent is as follows 1. Ainetallic door comprising a side-wall of sheet-metal having an opening therein, sheet-metal edge-strips of U-shaped crosssection secured to the edges of said Wall, and a Window-frame secured to said Wall about said opening, parts of said frame extending within the edge-strips at opposite sides of the door, substantially as set forth.

2. A metallic door comprisinga sheet- Inetal side-wall having an opening therein, edge portions of U-shaped cross-section at the edges of the side-wall, anda windowfraine secured to said Wall about said opening and having parts thereon extending within said edge-portions and bracing the saine, substantially as set forth.

3. A metallic door comprising a side-wall. of sheet-metal having an opening therein, sheet-metal edge-strips of U-shaped crosssection secured to the edges of said wall, a window-frame secured to said Wall about saidv opening, and offsets on said frame eX- tending within the edge-strips at opposite edges of the door, substantially as set forth.

4. A metallic door consisting of two sheetmetal side-Walls lspaced apart from each other and having openings therein one of which is larger than the other, edge-strips secured to the edges of said side-walls, a window-'frame lying between said side-Walls,

secured to the adjacent faces thereof and alininfr with the edges of said openings in the side-Walls, parts on said frame extending within said edge-strips and bracing the same, and a glass in said frame, substantially as set forth.

This specification signed and witnessed thisth day of June, 1908.
